--------------------------------------
Summary: Dedicated executors not invalidating stale LibCache
entries
Key: IMPALA-8763
URL: https://issues.apache.org/jira/browse/IMPALA-8763
Project: IMPALA
Issue Type: Bug
Reporter: Quanlong Huang
This is a follow-up Jira for IMPALA-8486. Dedicated executors won't receive any
catalog updates since they don't subscribe to the catalog-update topic. This
causes them unable to notice whether a libCache entry is stale.
We may need to introduce a new topic for the dedicated executors to subscribe
to invalidate the stale libCache entries.
